Please observe the safety instructions and warnings in these
operating instructions when using UVC light !
We recommend filling the bottom basket of the pond filter with
Zeolite (1.5 l) to ensure a larger surface and therefore an im-
proved cleaning effect.

➔
If the filter is slightly dirty, unscrew the dirt-drain screw and
push the foam filter down so that the dirt can be drained out
through the outlet.
➔
If it is very dirty, remove the foam filter and clean it under
running water.
6. Flush the whole filter out with water to ensure that all dirt
particles are removed.
7. If necessary, clean the UVC light, e.g. with a glass detergent.
Please read the paragraph on “How to Change the Lamp”.

then the coarse filter (black).
➔
Make sure the clips are properly re-attached.
9. Replace the holding-down devices so that they are angled
at 90° to one another.
➔
Important: position the first holding-down device towards
the universal connector.

must face one of the holding-down devices.
